🔥Terraformでクラスターを作った時にkubectlがTimeOutになる

sudo kubectl get nodes --output name

The connection to the server localhost:8080 was refused - did you specify the right host or port?

原因: 環境変数KUBECONFIGが設定されておらず(あるいはパスが見つからず)、参照が上手く行っていない。

解決: 

export KUBECONFIG=$KUBECONFIG:$HOME/<kubeconfigの場所>

# kubeconfig
resource "local_file" "kubeconfig" {
  content  = module.gke_auth.kubeconfig_raw
  filename = "kubeconfig-${var.env_name}" //ここのファイルのパスを上のexport文に代入する
}

今回は.tfファイルがkubeconfigを吐き出す設定なので、そこにパスを通す。
